' RADIATOR FOR FURNACES.

SPECIFICATION forming part of Letters PatentV No. 272,326, dated February 13, 1883.

Application led November 27, 1882. (No model.)

To all whom t may concern Be it known that I, DWIGHT S. RICHARD- SON, a citizen of the United States, residing in the city of Brooklyn, State of New York, have invented a certain new and useful Improvement in Radiators for Furnaces; and I (lo hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, making a part of this speciiication.

My invention relates to that part of the furnace termed the radi-ator, through which the gases and products of combustion received trom the body of the furnace pass before escaping into the chimney;` and it has for its object the more com plete and effective heating of the radiator by the gases as they pass through it. Y

In the drawings like letters indicate like parts.

Figure 1 is a View of the radiator in' connection with the body of the furnace, a portion of the radiator being broken awayto show my improvement. Fig. 2 is a sectional view vertically ofthe radiator and body of the furnace. Fig. 3 is a horizontal sectional View of the radiator alone above thediaphragm.

rlhe radiator as improved by me is made wholly of cast-iron, cast in one piece, and has a diaphragm or partition extending horizontally through the same, but having an opening at one end, thus dividing the radiator into an upper and lower chamber connecting Yas with each other.

The radiator as constructed by me usually surrounds the dome ofthe furnace, and is counected with the Sallie by lines, through which the gases and productsof combustion pass into it from the body. While this position ofthe radiatorv is the most desirable, as decreasing the height of the urnace, it may be placed eutir'ely above the dome, or in any position found desirable.

The nature of my invention is best understood by reference to the drawings, Figure 1 of which shows the radiatorA as surrounding the body or dome F of the furnace, and as connected therewith by the lines B B', Which open into the interior of the body.

through the radiator, and having in it the found desirable, (shown in Fig. 3,)

D is the partition, extending*horizontally" by which the gases and products of combustion pass from the lower to the upper chamber of the radiator. l

As willbe seen from Fig. 2, the products of combustion pass at once from the combustionchamber to the top of the dome, and are there deflected by the sides of the dome until they escape, by means ofthe dues B B', into the lower chamber of the radiator, through which they circulate in the direction indicated by the arrows, and then pass, through theopening d of the diaphragm, into the'upper chamber of the radiator, through which they pass in au opposite direction into the smoke-pipe S. The heatedsmoke and gases thus circulate through the radiator twice, thus securing a much greater and more effective heating-surface than is obtained with the radiators now used, consisting of a. single chamber. The radiator has one or the body of the furnace, and these flues are preferablysituated Lto ward or near the part or end of the radiator farthest from the opening d in the partition, so that the gases and products of combustion will circulate through the whole extent of the lower chamber before they pass into the upper chamber of the radiator, and for the same reason the hole S, by which the gases, Sac., escape into the chimney, is situated on the opposite side ot' the radiator from the opening d. At C is an opening, closed by means of a plate, for removing the ashes, o., which collect in the radiator.

Bymy improved radiator I thus obtain a greater quantity ot effective heat from the same amount of gaseous products or from the combustion. of thel same amount of coal. The radiator A is preferably cast solid or in a/ single piece, as thereby all joints, except where the iiues B B' connect with the body of the furnace, are avoided, and the gaseous products diaphragm D may be flat, as shown in the IOO drawings, or may be curved or angular, or with a corrugated or waved surface.

I am aware that in magazinestoves a heatingdrum -encircling a magazine and having a diaphragm dividing the drum int-o lower and upper ues has been made. I am also aware that in hot-air furnaces a drum in which the products are made to pass first to the top and then to the bottom of the same has been constructed. I do not claim either of these; but

What I claim is- 1. The combination, with the bodyof an airheating furnace, and encircling the dome 0f the combustion-chamber of the same,of asolid cast-iron radiator having a diaphragm or partition extending through the same, with an opening therein connecting the two chambers ot' the radiator, substantially-as and for the purposes set forth.

2. The combination, with the body ot'an airheating furnace, and encircling the dome ot' the combustion-chamber ofthe same, of a castiron radiator the bodg7 of which is cast in one piece, and having a diaphragm or partition provided with an opening, as set forth, eX- z5 tending horizontally through the same, all substantially as set forth.
